UK call forwarding guide

How to divert calls to Greetivo.

When a business starts using Greetivo, one of the quickest wins is getting inbound calls diverted cleanly to the number assigned to that business. Done properly, it means fewer missed calls, less front-desk pressure, and a more consistent first response for callers — whether you describe Greetivo as an AI secretary, AI receptionist, or AI personal assistant for business calls.

Built for UK operators Mobile and landline guidance is grouped around the providers UK businesses actually use.
Made for live use Shortcodes are presented clearly, with cancellation steps and practical notes beside them.
Before you start

Make the setup simple and safe.

The cleanest way to do this is to decide first whether you want every call to go to Greetivo, or only calls that you miss, cannot answer, or cannot receive. For many businesses, starting with unanswered or busy diverts is the least disruptive way to test the workflow before moving to a full divert-all setup.

Divert all calls Best if Greetivo is handling your front line in full and you want your phone not to ring at all.
Divert when busy or unanswered Best if you still answer some calls yourself but want Greetivo as cover when you miss one.
Divert when unreachable Useful for poor coverage, switched-off mobiles, or situations where you do not want callers to hit voicemail first.
Operator guide

Find your operator and use the right forwarding method.

Where a provider publishes a clear public shortcode table, you will see the exact setup, cancel, and check pattern here. Where a provider’s current public help pages favour handset settings instead, this guide uses that official route rather than guessing or inventing a code table.

Mobile operators

For most business mobiles, this is the fastest route to diverting calls to your Greetivo number.

Vodafone

Vodafone publishes a public code pattern and expects the destination mobile number in +44 format.

Divert all calls

Replace the first 0 with +44.

Important notes

  • Vodafone’s public help and device guides show a +44 format for mobile forwarding destinations.
  • If you are diverting to a number outside your normal allowance, charges may apply in line with Vodafone’s UK call charging rules.
Mobile Official settings route published

EE

EE’s current public help pages steer customers to the phone settings or the 150 automated menu, rather than a full public shortcode table for forwarding to any arbitrary number.

Divert all calls

Set up
Official route: on iPhone go to Settings → Call Forwarding → Forward To, or on Android open Call Forwarding in your phone settings and enter your Greetivo number.
Cancel
Turn the same setting off, or remove the divert via 150.
Check
Review the forwarding status in your handset settings.

EE Business also lets you set up or remove a divert through 150.

Divert when busy

Set up
Use the Call Forwarding / Voice calls menu on your handset, select the busy option, and enter your assigned Greetivo number.
Cancel
Disable the busy forwarding option in the same menu.
Check
Review the busy divert status in the same menu.

EE’s public help page confirms the settings route, but not a single generic shortcode table for this scenario.

Divert when unanswered

Set up
Use your handset’s no-reply / unanswered forwarding option and enter your assigned Greetivo number.
Cancel
Disable the no-reply forwarding option.
Check
Review the no-reply forwarding option in the same menu.

On some phones you can also choose the ring delay before diversion.

Divert when unreachable

Set up
Use your handset’s unreachable / unavailable forwarding option and enter your assigned Greetivo number.
Cancel
Disable the unavailable forwarding option.
Check
Review the unavailable forwarding option in the same menu.

Useful if you want out-of-coverage or switched-off calls to land with Greetivo.

Cancel all diverts

Set up
Turn all call-forwarding options off in your phone settings, or call 150 and choose the remove-divert option.
Cancel
Check

EE’s official business help page documents the 150 route for setup and removal.

Important notes

  • EE Business says diverting a call to another UK number is charged at the normal call rate for your plan, or comes out of your allowance if that number type is included.
  • If you prefer a fully operator-led route rather than handset menus, EE Business documents setup and removal via 150.
Mobile Official handset route published

O2

O2’s current official help pages mainly document handset-based call forwarding and voicemail-specific codes. For a non-voicemail destination such as Greetivo, the safest route is to use the phone’s call-forwarding menu and enter your assigned number there.

Divert all calls

Set up
Use your handset’s Call forwarding / Always forward menu and enter your assigned Greetivo number.
Cancel
Turn the same forwarding option off.
Check
Review the forwarding status in your phone’s call-forwarding menu.

O2’s public device guides show this route on current iPhone and Android help pages.

Divert when busy

Set up
Use the busy / when occupied option in your handset’s call-forwarding menu and enter your assigned Greetivo number.
Cancel
Turn the busy option off.
Check
Review the busy-forwarding status in the same menu.

O2’s voicemail guides use 901 for voicemail forwarding. For Greetivo, use the menu and your own assigned number.

Divert when unanswered

Set up
Use the no reply / unanswered option in your handset’s call-forwarding menu and enter your assigned Greetivo number.
Cancel
Turn the no-reply option off.
Check
Review the no-reply status in the same menu.

If your phone supports a timer, choose a ring delay that suits your workflow.

Divert when unreachable

Set up
Use the unavailable / unreachable option in your handset’s call-forwarding menu and enter your assigned Greetivo number.
Cancel
Turn the unavailable option off.
Check
Review the unavailable status in the same menu.

Useful if you want switched-off or out-of-coverage calls to land with Greetivo.

Cancel all diverts

Set up
##002#
Cancel
Check

O2’s official device guides publish ##002# as the clear-all code.

Important notes

  • O2’s official help pages clearly show voicemail forwarding to 901 and a cancel-all code, but they do not surface a clean public shortcode table for every non-voicemail forwarding scenario.
  • O2 lists 07 non-mobile and call-forwarding services separately in its charges guide, so check your tariff before sending high volumes of diverted traffic to any non-standard destination.

  • Three community guidance also notes that the forwarding setting is tied to the SIM rather than just the handset.

Important notes

  • Virgin Media says Call Divert is a paid home phone feature and that enabling it disables Free Voicemail until the divert is removed or you move to a voicemail feature that works alongside it.
  • Virgin’s help page also notes the mobile experience is usually managed from your handset settings instead of landline star codes.

Frequently asked questions

Quick answers before you activate a divert.

These are the questions business users most often ask before diverting calls to an answering service, AI receptionist, or AI personal assistant number.

Which number should I enter when setting up a divert to Greetivo?

Use the exact Greetivo number assigned to your business. If your operator says to replace a leading 0 with +44, do that before you save the rule.

Should I divert all calls or only missed calls?

If you want Greetivo to answer every inbound call, use divert all calls. If you only want cover when you are busy, unanswered, or unavailable, choose the matching conditional divert instead.

Will diverted calls cost extra?

Often, yes. Several UK providers say diverted calls are charged as though you made an outbound call from your line to the destination number, unless your plan includes that type of call.

Why does one operator section show settings instead of star codes?

Some operators publish a clean public shortcode table. Others currently surface handset-menu steps or voicemail-only examples in their public help. Where a full official generic code table was not clearly published, this page uses the safest verified route instead of guessing.

Verification and trust

Sources used for this page.

This page was built around current public operator help resources and official-domain support material, prioritising operator help pages wherever they clearly published the information. Where a network’s main public help pages were less complete, the safest documented route or official-domain community guidance has been flagged accordingly.

This file includes FAQ schema below because it is genuinely useful for this page, matches visible content, and helps search engines understand the practical call-forwarding questions businesses commonly ask before diverting calls to Greetivo.
